The invention discloses an agriculture straw crusher easy to use. The agriculture straw crusher includes a base; a bottom of the base is fixedly connected to two symmetrical supporting columns; a buffer cavity is formed in a bottom of each supporting column; two symmetrical clamping grooves are formed in an inner wall of each buffer cavity; and an inner top wall of each buffer cavity is fixedly connected to a damping spring. According to the agriculture straw crusher easy to use, fixing columns and the supporting columns can move vertically, vibration of the crusher can be effectively relieved, and shaking and dumping of the crusher can be avoided, the anti-skid performance can be achieved, great sliding of the crusher can be avoided, the stability is excellent, crushed materials can be effectively guided and discharged, vibration acted on a motor and a supporting plate can be effectively buffered, the relative stability of the crusher can be ensured, and the crusher is easy to use.
